BOSTON — Bruins head coach Claude Julien wouldn’t reveal this morning who’s going to start in Nathan Horton’s vacated spot on the first line tonight in Game 4 of the Stanley Cup Final.

However, he did confirm that, as expected, rookie Tyler Seguin would get Horton’s vacated lineup spot.

Seguin pretty much understood that when he spoke to the media after the team’s morning skate at TD Garden.

“It’s about being good in your defensive zone and hopefully that will lead to offensive opportunities,” said Seguin. “I feel like if I go out there worried I’m going to make mistakes, that’s when I’m going to make them. If I go out there confident and focused, I shouldn’t make any. So that’s my mindset going into tonight.”

Just as Shawn Thornton didn’t know until after warm-ups his streak of healthy scratches was going to end at seven in Game 3, Seguin didn’t know he was out until then.

“Obviously, you’re going to be mad when you’re not playing,” said the rookie, who has been point-less since his four-point explosion in Game 2 of the Eastern Conference Final. “But I wished Thorty lots of luck and just went and did my thing in warm-ups and then went to the workout room.”

Seguin said that his performance in a couple of Boston’s bigger games in the last round helped boost his confidence and that watching Game 3 of this series from the press box helped him learn some tendencies of the other team.

He also feels “rested and energized.”

We don’t know for sure what line he’ll be skating on tonight. We just know that he’s going to be a big part of the committee that’ll try to make up for the loss of Horton’s production.

Agree with above statements, I really believe that Seguin or Ryder would shoot where Lucic tries for the extra pass. I also think Ryder and Seguin play better when they are on a line with more skilled centers, neither guy really can carry a line by himself and they both have great shots. They really need that setup pass from a skilled center.

The match-up with the Canucks third line, plus the fact that the Bruins get that last change, makes this the perfect time for Seguin to get time on the first line. And if he doesn’t get PP minutes, I may vomit.

I bet he takes Horton’s spot on the 1st. Cam explained how Segz isn’t a good matchup against the nucks’ big physical 3rd line, and Julian has already shown he doesn’t want to break up his second line. The fourth line should stay intact as well. You heard it here first

I am so damn pumped for this game tonight, men. Our Bruins have a chance at something real big. There has been ONE game that has been a blow out; the B’s won that one. The other games, separated by one goal a piece. The Bruins have what it takes to play against this VAN team no matter the style. Buckle up, boys, tonight’s going to be a big game.

NO, you don’t want to see run & gun offense. With that kind of mentality means more penalties, especially for the Bruins who have a hard time clearing their zone. & with more PP means more goals for Van.

Bruins need to play a physical game just like last, especially on those 2 Swedes who don’t like to be hit.(Kaberle too!!!)

Bruins need this game tonight. They cannot go down 3-1. MUST WIN.

& Seguin better step it up & show his determination & speed & forecheck. I know he is a rookie but we are counting on him to contribute.

Vancouver has surprised me with their level of physicality. They are not the Flyers and they are not the Bolts, they can play both the skills game and the hitting game. I’d say we have an edge in the hitting game, or more specifically, the grinding game, winning the battles in the corners and keeping control of the puck. I do have this feeling though, that we can win the run and gun game too. We have the skills to keep up enough, but we really excel at keeping our defensive responsibilities in mind even when the pace picks up, VAN can’t match us in that. So I’d like to see some more wide open hockey tonight, and I look at the Pev – Kelly – Segz line to provide some of that.
